VARIETY DENOMINATION

‘DrisStrawFourteen’

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct strawberry cultivardesignated ‘DrisStrawFourteen’ and botanically known asFragaria×ananassa. This new strawberry cultivar was discovered inMonterey County, Calif. in May 2005 and originated from a cross betweenthe proprietary female parent ‘159K312’ (unpatented) and the proprietarymale parent ‘128K296’ (unpatented). The original seedling of the newcultivar was first asexually propagated by stolons or tissue culture ata nursery in Shasta County, Calif.

‘DrisStrawFourteen’ was subsequently asexually propagated in ShastaCounty, Calif. and underwent further testing in Monterey County, Calif.for five years. The present invention has been found to retain itsdistinctive characteristics through successive asexual propagations viastolons and tissue culture.

DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs show typical specimens of the newcultivar at various stages of development as nearly true as it ispossible to make in color reproductions. The photographs were taken from9-month-old plants.

DESCRIPTION OF THE NEW CULTIVAR

The following description of ‘DrisStrawFourteen’ is based onobservations taken in Monterey County, Calif. from 2005 to 2009. Thisdescription is in accordance with UPOV terminology. Color designations,color descriptions, and other phenotypical descriptions may deviate fromthe stated values and descriptions depending upon variation inenvironmental, seasonal, climatic, and cultural conditions.‘DrisStrawFourteen’ has not been observed under all possibleenvironmental conditions. The botanical description of‘DrisStrawFourteen’ was taken from 9-month-old plants and the botanicaldescriptions of the comparison varieties, ‘San Juan’ (U.S. Plant Pat.No. 12,899) and ‘Driscoll Lanai’ (U.S. Plant Pat. No. 15,145), weretaken from 10-month-old plants and from 8-month-old plants,respectively. Color terminology follows The Royal Horticultural SocietyColour Chart, London (R.H.S.) (2001).
